Because sound needs particles to travel through ; when a sound from inside one helmet is made, the particles vibrate the surrounding particles therefore vibrating the other astronauts helmet particles ( as they are touching) allowing him to hear the sound.

Would astronauts on the Moon be able to hear a rocket engine?
I hope so. However, if they see something that would be noisy on the Earth, but in space, like a rocket firing, they would not hear it in space, because sound needs a medium to travel through, like air. There is no air in space, it is mostly a vacuum. So the only sounds an astronaut should hear are his radio, his breathing and anything tapping on his helmet (the air in the helmet will transmit sound waves to his ears).
What does to be broke mean in idiomatic expression?
To be broke means to have little or no money. You hear it as "I'm too broke to eat at a restaurant today," or "I'd go with you, but I'm broke." Sometimes, you might hear it used to refer to a third person. This might be "She spent all her money on clothes, so now she's broke until payday."

If an astronaut's radio broke what could they do to hear each other speak?
Touch helmets.
Why could they hear each's other voices when their helemets were touching?
When their helmets were touching, vibrations from their voices could travel through the helmets and into each other's ears, allowing them to hear each other. This is similar to how a stethoscope works by transmitting sound waves through a solid medium.
Why do astronaunts on the moon have to communnicate by radio even when close to one another?
Sound needs a medium to be transmitted in ... when we hear a sound it's just moving air. The air moves on our eardrums and THAT is how we hear .. on the moon there's basically no air for the sound to travel in .... .... it would be possible for astronauts on the moon to touch their helmets together and talk that way, if for example their radio was not working. ____________________________________________ They don't. Sound carries from the astronaut's mouth to his helmet, and if two astronauts were to touch their helmets together, the sound would be carried clearly to the second astronaut. However, if they are not actually touching helmets, the sound cannot be transferred through the vacuum of space. In that case, they would need to use either radio or some visual means of communication; visual hand signals, or a laser link, something like that. Or, for medium range verbal communication in space, you could use a version of the "two tin cans and a string" telephone. Attach a wire from one helmet to the other, and pull away so there is some tension in the string. Speak normally. The vibrations of the air inside your helmet will cause a vibration in the string. The vibration in the string will cause vibration in other helmet, and you will be able to hear. Not as well as a radio, and not as clearly - but it will work.
